ʻO ke poʻo ninini ʻana i ke kūlana hoʻomalu o kamīkini hoʻohāhā kiʻekiʻeme ke poʻo ninini a me ka lima i hoʻonohonoho ʻia ma waho o ke poʻo ninini.Hoʻonohonoho ʻia kahi cylinder hydraulic vertical ma waena o ka lima a me ke poʻo ninini.Hoʻopili ʻia ke kino cylinder o ka hydraulic cylinder vertical me ka lima.ʻO ka valve Hoʻopili ʻia ke koʻokoʻo me ke poʻo ninini.I ka manawa like, aia kahi ala alakaʻi ākea ma ke kino mīkini hoʻoheheʻe sima, a hāʻawi ʻia kahi puka puka alakaʻi e pili ana i ke ala alakaʻi ma ka lima.Hāʻawi ʻia kahi cylinder hydraulic ākea ma waena o ke kino mīkini hoʻoheheʻe kiʻekiʻe a me ka lima.Hoʻopili ʻia ke kino cylinder o ka hydraulic cylinder horizontal me ke kino o ka mīkini hoʻoheheʻe kiʻekiʻe, a hoʻopili ʻia ke kumu valve me ka lima.Loaʻa i ka hiʻohiʻona pono nā mea maikaʻi o ka mālama hana a me ka hana kiʻekiʻe.

ʻO nā ʻāpana ʻelua A a me B o kamīkini pahu polyurethaneua hoʻohālikelike pono ʻia a hoʻoulu ʻia i ka wikiwiki kiʻekiʻe, a hāʻawi ʻia nā ʻāpana ʻelua ʻo A a me B i ke poʻo hui ʻana e ʻelua mau mīkini mika kiʻekiʻe.Ma hope o ka hoʻoulu ʻana i ka wikiwiki a me ka ikaika, hoʻoheheʻe ʻia ka wai mea e hana i ka huahana i makemake ʻia.

ʻO kahi mea kanu hoʻoheheʻe kiʻekiʻe piha i nā ʻōnaehana penei: ʻōnaehana kahe waiwai, ʻōnaehana metering, ʻōnaehana kaapuni ea, ʻōnaehana hoʻomehana, ʻōnaehana hoʻomaʻemaʻe, nā mea hana kūikawā no ka polyurethane foam infusion a me ka huʻa.ʻOiai ka lōʻihi o ka hui ʻana o ka polyurethane maka kumu (isocyanate a me polyether polyol component) e hālāwai me nā hōʻailona hana o ka hana.Hana ʻia ia me ka polyether polyol a me ka polyisocyanate ma ke alo o nā mea hoʻohua, nā mea hoʻoheheʻe, nā emulsifiers a me nā mea hoʻohui kemika ʻē aʻe, ma hope o ka hoʻoulu ʻana o ke kemika a me ka huʻa.ʻEkolu ʻano kaʻina hana hoʻohua i loko o ka mīkini hoʻoheheʻe kiʻekiʻe: pre-polymer method, semi-polymer method and one-step foaming pre-polymer method foaming method is to make pre-polymer (white material) and (black material) mua, a laila hoʻohui i ka wai, catalyst, surfactant, nā mea hoʻohui ʻē aʻe i loko o ka pre-polymer i hui ʻia ma lalo o ke kiʻekiʻe-wikiwiki hoʻoulu ʻana no ka hoʻoulu ʻana, ma hope o ka ho'ōla ʻana i kahi mahana hiki ke matured.ʻO ke kaʻina hana hoʻohāhā o ke ʻano semi-prepolymer ʻo ia ka hana ʻana i kahi ʻāpana o ka polyether polyol (mea keʻokeʻo) a me ka diisocyanate (mea ʻeleʻele) i loko o kahi prepolymer mua, a laila e hoʻohui i kahi ʻāpana o ka polyether a polyester polyol a me diisocyanate, wai, catalyst, surfactant. , nā mea hoʻohui ʻē aʻe, a me nā mea ʻē aʻe.Hoʻohui ʻia ka polyether a i ʻole polyester polyol (keʻokeʻo) a me ka polyisocyanate (ʻeleʻele), ka wai, catalyst, surfactant, blowing agent, nā mea hoʻohui ʻē aʻe, etc.ʻO ke kaʻina hana hoʻoheheʻe hoʻokahi ka hana maʻamau i hoʻohana ʻia i kēia lā.Aia kekahi ʻano hana hoʻohāhā manual, ʻo ia ke ʻano maʻalahi loa, kahi e kaupaona pololei ʻia ai nā mea maka a pau, waiho ʻia i loko o kahi pahu a laila hui koke ʻia a hoʻokomo ʻia i loko o ka mold a i ʻole ka hakahaka e hoʻopiha ʻia me ka huʻa.Nānā: Pono e kaupaona ʻia ka polyisocyanate (ʻeleʻele) i ka hope.

ʻO kamīkini pahu polyurethanee hu'a ma'amau i ka lumi wela, a ma'alahi ke ka'ina hana.E like me ke kiʻekiʻe o ka hana mechanization, hiki ke hoʻokaʻawale ʻia i loko o ka manual foaming a me ka mīkini pahu;e like me ke kaomi o ka huʻihuʻi, hiki ke hoʻokaʻawale ʻia i loko o ka haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa;e like me ke ʻano hana hoʻoheheʻe, hiki ke hoʻokaʻawale ʻia i ka ninini ʻana i ka puaʻa a me ka pīpī ʻana i ka pua.
